This silent mod is for EVERY 3d printer with Nema17 motors.
The silicone parts reduce the noise in a so drastic matter, the loudes part on the printer is the cooling fan for the hotend now.

It is important that the Nema17 motors and the bolt to hold them have no direct contact to the frame. For this purpose the silicone washers are very important.

The part order is:
bolt - metal washer - silicone washer - frame - silicone plate for Nema17- Nema17 motor

For additoinal vibration reduction i have added a mold for the rubber feet.

If this mod changed you life feel free to donate. :D


Added the positives for people who want to print the dampers in flexible filament.

How did you remove the silicone?

The silicone is self releasing after its cured.

What kind of silicone are you using? I've tried just getting some from Amazon. I squeeze some into the mold, but it just got stuck in there and there's no way for me to get it out in one piece.

So, can you please tell me what kind of silicone you're using and how you get it to pop out in the end? :)


After a curetime (depending on the silicone can be 30 minutes to a couple hours) the silicon does not stick to anything except silicone itselft. You can pull it out without any problems out of the mold. If that is not the case with your silicone you might have the wrong silicone or not use it in the proper way. You can post a link to the silicone you bought, maybe we can help you further then.

I think you'd get a lot more hits if you relabelled it nema damper because that is what I searched for and this didn't come up. However I saw this browsing other stuff

Thanks for the tip!

basically a nema damper

Thanks, that's a very clever idea ;-) btw what did you use as filling material?
